Gas and Diesel Fuel Dock

 

The Harbor Marina fuel dock is located at the first marina inside the channel entrance of Three Mile Harbor, less than 10 minutes from the open waters of Gardiner's Bay. Harbor Marina has been a proud supplier of the high quality ValvTect marine grade gasoline and diesel fuels since the mid-1980's and sells a 89-octane ValvTect gasoline and the marine grade Ultra-low sulfur diesel . Both fuels contain ValvTect branded additives that are specifically suited for all engines in the marine environment. Mercury 4-Stroke Verado Outboards over 250HP are recommended to use Gasoline rated at 91-Octane and these engine owners can find ValvTect Octane Boost in the Harbor Marina Ship's Store.

To access the fuel dock, boaters should clear the green can (#8) in front of the marina, leaving it to their north side (see photo below). Recent soundings show over 7' of water at low tide both in the approach to the fuel dock and beyond the dock if a wide turning area is required. The tidal range is 3'.

Harbor Marina staff will be glad to assist your approach during the boating season and are available on Channel VHF 9 or by prior arrangement at 631-324-5666, ext. 1.

Shoreside, boaters will find clean restrooms, a retail store with a full line of marine products and accessories, watersport items, snacks, drinks, ice cream, gifts, sundries, and parts for most marine engines and systems.
